Chimp Test guide

Numbers appear on the grid, then hide behind tiles. Click them in order from memory. Each round adds a number, in the test made famous by chimpanzees.

  • 3 strikes
  • No clock

Goal

Click numbered squares in order after the numbers have been hidden.

How to play

  • Numbers appear scattered across the grid.
  • Click number one. The moment you do, every remaining number is covered.
  • Click the rest in ascending order from memory.
  • Clear a board and the next has one more number. A mistake costs a strike.

Where the name comes from

The test mirrors a working-memory task in which young chimpanzees outperform human adults at holding a briefly glimpsed spatial layout. The layout is what you need, not the numbers - take in the whole board at once rather than reading it in sequence.

Scoring

  • Your score is the highest count of numbers you placed correctly.
  • There is no clock; the pressure is entirely on memory.
